panic: biodone2 already

[Lars Nordlund <lars.nordlund%hem.utfors.se@localhost>]

Hi

Got this panic while writing a DVD+RW last night. I am running NetBSD
4.99.72/amd64. Kernel message hand-copied from screen..

panic: biodone2 already

That's it. Anyone has any clues? Here's the dmesg by the way:
